IMPROVEMENT IN WATER-COOLERS.

Specification forming part of Letters Patent No. 140,712, dated July 8, 1873; application tiled May 26, 1873.

To all whom vit may concern:

Beit known that I, WILLIAM S. KIMBALL, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Attachments to Water-Coolers for Filtering Purposes; and I do herebydeclare the following to be a clear and exact description of the nature thereof, suflicient to enable others skilled in the art to which my invention appertains to fully understand, make, and use the same,reference being had to the accompanying drawings makpart of this specification, in whichf Figure 1 is a side elevation of the device illustrating my invention. Fig. 2 is a central vertical section thereof in line a." x, Fig. 1.

Similar letters of reference indicate corresponding parts in the two figures.y

This invention relates to a receiver adapted to be fitted on the cooler and filter the Water before it enters the body of the cooler; and consists in a filtering-block in the receiver, and fitted on a tube or pipe which communicates with the cooler. It also consists in a pipe projecting above the bottom of the re-' ceiver to prevent sediment entering the cooler. It also consists in a pipe in the receiver for passage of displaced air. It also consists in the combination of parts.

Referring to the drawings, A represents a water-cooler, which is of ordinary form and Bv represents a vessel or receiver, whose diameter or dimension in crosssection is equal to that of the inner face of the cooler. A pipe, C, extends through the bottom of the vessel B, and its upper end a projects above the bottom. On the inside of the vessel B there is arranged a vertical pipe, D, which is secured at one end, b, to the side of the vessel near its top, and the other end, c, passes through the bottom E of .the said vessel, so. that the.pipe does not open into the vessel, but opens outside thereof, respectively,

near the top and at the bottom of the vessel, as at b c. F represents a iiltering-block, which is fitted centrally in the vessel B without materially alfecting the capacity of the vessel,

and is secured to the upwardlyprojectin g por- "tion of the pipe C, so that the block is removably fitted on the pipe, and excepting the opening for the pipe (l, the bottom of the receiver is intact. The lid Gis packed, and is adapted to fit either the vessel B or the cooler A.

The operation is as follows: The vessel or receiver is fitted on the cooler and illed with water, which is to be filtered prior to its entrance into the cooler. The cooler now communicates with the atmosphere by means of the pipe D. Before the water can rea-ch the pipe C it must pass through the block F, and is consequently subjected to the filtering action of the said block, so that the water reaches the pipe C in a pure state, and is thus passed into the cooler.

It is evident that as the water passes out of the vessel quite slowly and is resisted by the filter F, its sediment collects on the bottoni of the receiver below the top of the pipe C, andthus cannot seek the said pipe or is not disturbed by the water as it passes through the filter. As the Water enters the cooler, the displaced air will escape through the pipe D, as indicated by arrows 2, and thus the free passage of the water from the pipe C into the cooler is not resisted.

When the water is filtered, the vessel may be removed and its lid placed on the cooler. The remaining Water, sediment, and dirt can then be discharged from the vessel, and, if desired, the vessel again applied. to the cooler, and replenished as often as deemed advisable or necessary. The ice Will be placed in the vessel or cooler, or both, at option.

When the block requires cleaning, it is merely slipped off of the pipe C, and may then be washed, after which it is again readily applied in place.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. The filtering-block F in the receiver, and fitted on a tube communicating with the cooler, substantially as and for the purpose set forth.

2. The combination, with the cooler A, of

` rrron.

the vessel B having the upwardly-projecting D, substantially as and for the purpose set pipe C, and the lter F fitted on said pipe, forth.

substantially as and for the purpose set forth. The above signed by me this 16th day of y 3. In combination with 'the cooler A, the April, 1873.

pipe D of the vessel B, substantially as and W. S. KIMBALL. for the purpose set forth. Witnesses:

4. The combination with the cooler, A, of JOHN A. WIEDERSHEIM, the vessel B with pipe C, filter F, and pipe MILLARD F. 'WALTON
